[QUOTE=Bill Berson;31480]A private pilot SEL can fly a homebuilt seaplane on water or twin engine on land or water or even a helicopter as long as it is solo.

Bill, I don't think you're correct about homebuilt twins. The rep for Aircam told me I need a multi-engine rating to fly it solo or + passenger. It's a fabulous airplane but this is the reason sales are low. I know you're correct for single seat heli like the Mosquito.
